SPRING-WHEEL.

To all whom it may concern:

Be it known that I, ALVIN R. McENTmn, a citizen of the United States,residing at Folsom, in the county of Bar-tow and State of Georgia, haveinvented certain new and useful Improvements in Spring-Vheels, of whichthe following is a specification, reference being had to theaccompanying drawings.

This invention relates to new and useful improvements in vehicle wheelsand has for its object the provision of a spring wheel, the constructionof which is such as to positively prevent jolting or jarring of thefelly and its associated parts incident to traveling over rough, unevenroads.

Another object of the invention is to provide a spring wheel which willpossess advantages in points of efliciency and durability, isinexpensive of manufacture and at the same time is simple inconstruction and operation.

With the above and other objects in view, the invention consists in thenovel features of construction and the combination and arrangements ofparts hereinafter more fully described, pointed out in the claims andillustrated in the accompanying drawings, in which I Figure 1 is a sideelevation of a spring wheel constructed in accordance with my invention;Fig. 2 is an enlarged longitudinal sectional view of a fragment of thewheel; Fig. 3 is a sectional view on the line 33 of Fig. 2 and Fig. 4;is a sectional view on the line 4L4C of Fig. 2.

Referring more particularly to the drawings, I indicates the hub havinga plurality of radially projecting spokes 2 which are secured at theirouter ends by means of the felly 3. A hub casing 4 is secured to the huband provided with a plurality of radial openings or sockets 5 adapted toreceive the inner ends of the auxiliary spokes 6. The outer end of theauxiliary spokes are disposed through the spaced openings 7 in thefelly, and the extreme outer ends of said auxiliary spokes are enlarged,as shown at 8, and adapted to support the outer rim 9. Slidably mountedon the auxiliary spokes 6 are the coil springs 10 which are arrangedbetween the hub casing 4 and the adjusting nuts 11 which are threadedonto the spokes 6, the tension of said springs being adjusted by meansof said nuts.

U-shaped brackets 12 are secured to the Specification of Letters Patent.

inner side of the rim 9 by means of the screw bolts 13, said bracketshaving their ends provided with openings adapted to receive the ends ofthe rods 15, said rods having their central portion mounted in theelongated openings 16 formed in the enlarged ends 8 of the auxiliaryspokes 6. Coil springs 17 are mounted on the rods 15 and disposedbetween the ends 8 of the spokes 6 and the sides of the brackets 12. i

A dust guard 18 is provided and adapted to inclose the hub casing 4: andthe coil springs 10, said guard being formed of two mating sectionsprovided with circumferentially disposed ears 19 through which arepassed bolts 20 whereby the sections of the guard 18 are securelyfastened together. The springs 17 are also inclosed by means of the dustguard 21 secured to the outer rim of the wheel.

It will be understood that either a steel or rubber tire may be securedto the rim 9, as desired.

From the foregoing description taken in connection with the accompanyingdrawings, the operation of my improved resilient wheel will be clearlyunderstood. In the practical use of the device, any shock or stresswhich is imposed upon the tread surface of the tire at any point will betaken up and absorbed by the springs 10 and 17, and consequently theshock will not be trans mitted to the hub and thence to the body portionof the vehicle, but will be practically dissipated.

While I have shown and described the preferred form of my invention itwill be obvious that various changes in the details of construction andin the proportions may be resorted to for successfully carrying myinvention into practice without sacrificing any of the novel features ordeparting from the scope thereof.

Having thus described the invention what is claimed is 1. In a vehiclewheel, the combination of a hub, a plurality of radial spokes projectingtherefrom, a felly secured to the outer end of said spokes, a hub casingsecured to said hub, having a plurality of radial openings formedtherein, auxiliary spokes having their inner ends slidably mounted insaid openings, an adjusting nut threaded on said auxiliary spokes, coilsprings arranged between said hub casing and nuts, an enlarged endformed on the outer end of said auxiliary spokes, having elongatedopenings therein, an outer rim supported by rim, rods having their endsmounted in said brackets and disposed through the elon gated openings inthe ends of the auxiliary spokes, and coil springs mounted on said rodsand arranged between the ends of the auxiliary spokes and said brackets.

2. In a Vehicle wheel, the combination of a hub, a casing therefor,spokes having their inner ends slidably mounted in said casing,adjusting nuts threaded on said spokes, coil springs mounted on thespokes and arranged between said casing and adjusting nuts, a dust guardinclosing said casing and springs, enlarged ends formed on said spokes,hav- Copies of this patent may be obtained for ing elongated openingsformed therein, a rim supported by the outer ends of said spokes,brackets secured to the inner side of said rim, having openings formedtherein, ro ds having their ends mounted in said openings and disposedthrough the elongated opening in the ends of the spokes, coil springsmounted on said rods and arranged between the ends of the spokes andsaid brackets, and a dust guard secured to the outer rim of the wheeland adapted to inclose said springs.

In testimony whereof I hereunto aifix my signature in the presence oftwo witnesses.
